Associations between variables of obstructive sleep apnoea and insulin sensitivity index(ISI) in females of different age groups
| ISI <50 yrs | ISI ≥50 yrs | p-value(interaction) | |
| Subjects n | 140 | 204 | |
| AHI# | -0.29 (-1.01–29.5) | -0.09 (-0.40–0.21) | 0.977 |
| ODI# | -0.41 (-1.26–0.44) | -0.16 (-0.47–0.16) | 0.882 |
| Minimal saturation | -0.02 (-0.15–0.12) | 0.11 (0.04–0.19) | 0.058 |
| % of the night with saturation <90% | 0.13 (-0.06–0.33) | -0.08 (-0.17– -0.004) | 0.012 |
Unless otherwise stated, results are presented as β-values (95% confidence interval) from multiple regression analysis adjusting for age, waist-to-hip ratio, level of activity, smoking and alcohol consumption. AHI: apnoea/hypopnoea index; ODI: oxygen desaturation index. #: results are calculated for an increase of 10 units.
